WALL STRUCTURE OF AUTOMOBILE AND MANUFACTURING METHOD OF THE SAME

To suppress insufficient filling of a foamed body in a curved part of a planar member structuring a wall structure of an automobile.SOLUTION: A wall structure of an automobile includes a first planar member 14, and a second planer member 18 which is arranged opposite to the first planer member with a space. An opposite wall part is formed by at least a part of the planer members 14, 18, and the opposite wall part has curved parts 34, 36. A foamed body 52 is arranged over the curved part 36 and pairs of plane parts 38, 40, 42, 44 extending from both ends of the curved part 36 between the two planar members 14, 18. In a region with the foamed body 52 arranged, an interval between the planar members 14, 18 at the curved parts 34, 36 is smaller than an interval between the planar members 14, 18 at the plane parts 38, 40, 42, 44.SELECTED DRAWING: Figure 6 【課題】自動車の壁構造体を構成する面状部材の湾曲部における発泡体の充填不足を抑制する。【解決手段】自動車の壁構造体であって、第一面状部材１４と、この第一面状部材に対し間隔を空けて対向配置された第二面状部材１８とを備え、この面状部材１４、１８の少なくとも一部で対向壁部が形成され、この対向壁部が湾曲部３４、３６を有し、二つの面状部材１４、１８の間において湾曲部３６とこの湾曲部３６の両端から延びる一対の平面部３８、４０、４２、４４とにわたって発泡体５２が配置されており、発泡体５２が配置されている領域において湾曲部３４、３６での面状部材１４、１８同士の間隔が平面部３８、４０、４２、４４での面状部材１４、１８同士の間隔よりも小さくなっている。【選択図】図６
